Casa Della Mozzarella
Time Out says
The best mozzarella in New York is a hotly-contested title, but few would argue with this Little Italy institution’s claim on the crown. Just ask anyone who waits in the snaking line for one of the sandwiches piled high with the namesake cheese. The best order lets the mozzarella shine: Try a simple prosciutto and muzz, served with a drizzle of balsamic vinegar on crusty hero bread.
